Abstract

The application provides a reactive power compensation optimizing configuration method and a reactive power compensation optimizing configuration system. A problem of transient voltage instability in an electric power system is solved from an angle of dynamic reactive power compensation according to low voltage maintenance time of each node in each fault condition. An optimal compensation place and optimal compensation capacity can be obtained via two optimizing models established by the reactive power compensation optimizing configuration method and the reactive power compensation optimizing configuration system, a global optimal compensation result is obtained, and system operation safety and stability are ensured.

Description

Technical field [0001] The invention relates to the technical field of power systems, and in particular to a reactive power compensation optimization configuration method and a reactive power compensation optimization configuration system. Background technique [0002] In recent years, multiple blackouts worldwide have been caused by voltage instability. Moreover, with the continuous improvement of the complexity and voltage level of the power grid, the increasing load and the continuous implementation of large AC and DC interconnected power grids, the problem of transient voltage instability after a fault occurs in the power system has become increasingly prominent. [0003] One of the key factors leading to transient voltage instability is the insufficient dynamic reactive power support of the power system. Although there are some studies on the optimal configuration of system reactive power compensation, most of them use static voltage stability analysis methods; For example, a...
